I write the code below but it doesn't show anything on the chart and i dont know why? #property indicator_chart_window void OnStart() { double weekly_open = iOpen(NULL, PERIOD_W1, 0); double daily_open = iOpen(NULL, PERIOD_D1, 0); // Draw the weekly open as a line on the chart ObjectCreate("weekly_open", OBJ_HLINE, 0, Time[0], weekly_open); ObjectSet("weekly_open", OBJPROP_COLOR, Blue); // Draw the daily open as a line on the chart ObjectCreate("daily_open", OBJ_HLINE, 0, Time[0], daily_open); ObjectSet("daily_open", OBJPROP_COLOR, Red); } This should show 2 lines on graph for daily open and weekly open

Your code works fine for me. For a "belt and braces" approach, try the following. #property indicator_chart_window int start() { ObjectCreate(0,"weekly_open",OBJ_HLINE,0,Time[0], iOpen(NULL, PERIOD_W1, 0)); ObjectSet("weekly_open", OBJPROP_COLOR, clrBlue); ObjectMove(0, "weekly_open", 0, Time[0], iOpen(NULL, PERIOD_W1, 0)); ObjectCreate("daily_open", OBJ_HLINE, 0, Time[0], iOpen(NULL, PERIOD_D1, 0)); ObjectSet("daily_open", OBJPROP_COLOR, clrRed); ObjectMove(0, "daily_open", 0, Time[0], iOpen(NULL, PERIOD_D1, 0)); return(0); }
